The Cole & Mason Self-Watering Potted Herb Keeper is an attractive and highly functional tool for keeping fresh herbs alive for longer. Economical, easy to use and innovative. Whether cut or potted, herbs need water and don't like to be overcrowded. Their stems and leaves are delicate. Over-handling should be avoided to prevent damage. Enter the Cole & Mason Self-Water Herb Keeper. The use of a hydro-felt pad allows herbs to draw water as desired, requiring 40% less watering. Pads can be rinsed with clean water (4 pads included). The carbon steel container is covered for less evaporation and can hold approximately 10 oz. of water. Fill the water reservoir with the conveniently placed pour spout.
